US lawmaker wants gov't to enforce regulation to ensure 'chipmakers conduct adequate due diligence on their customers' — House member calls for Biden-era export control to be enforced

U.S. House Select Committee on China Chairman John Moolenaar has urged the U.S. government to enforce the existing semiconductor export control measures, particularly the 'Foundry Due Diligence Rule' ... Read original →

U.S. lawmakers are pushing for stricter enforcement of semiconductor export controls, highlighting gaps in current due diligence practices, especially concerning TSMC’s role in supplying advanced chips to Chinese entities. This move will compel global foundries to tighten customer vetting, directly impacting Huawei, Sophgo, and others seeking access to 3nm and EUV chips. The ripple effect will drive a resurgence in 14/16nm production, accelerating domestic alternatives. Companies will face increased compliance costs, prompting shifts toward regional partnerships to mitigate legal exposure. In the medium term, this policy will reshape global chip supply chains, pushing China toward self-reliance in AI accelerators and design tools, while reinforcing the strategic importance of semiconductor policy in geopolitical competition.
